    Abstract: We compare observations of the non-flaring solar corona
    made simultaneously with Hinode/XRT and with RHESSI. The analyzed
    corona is dominated by a single active region on 12 November 2006.
    The comparison is made on emission measures. We derive emission
    measure distributions vs temperature of the entire active region
    from multifilter XRT data. We check the compatibility with the total
    emission measure values estimated from the flux measured with RHESSI
    if the emission come from isothermal plasma. We find that RHESSI and
    XRT data analyses consistently point to the presence of a minor
    emission measure component peaking at log T ~ 6.8-6.9. The
    discrepancy between XRT and RHESSI results is within a factor of a
    few and indicates an acceptable level of cross-consistency.
